This paper presents a new topology of optimum maximum voltage angle and current total harmonic distortion (CTHD) of uninterruptible power supply (UPS) on three level single phase photovoltaic (PV) - wind power hybrid inverter. It consists of four main circuits; they are a hybrid controller circuit, a charger circuit, a pulse driver and full bridge circuit. Its main energy sources are a PV array and wind power generation. In this research, a new technique to optimize the CTHD is by changing maximum voltage angle of the three level waveform that created by a microcontroller PIC16F627A-I/P and searched the lowest CTHD. This inverter is completed by stand by UPS, when the main power source fails, the battery can power the inverter and the microcontroller controls the UPS transfer switch. The result shows that for lamp load of 10 W, the lowest CTHD is obtained when the maximum voltage angle is 1340. [ABSTRACT FROM PUBLISHER] |
